According to the equipartition theorem, the molar heat capacity of a monatomic ideal gas
  a. depends on temperature.
  b. is larger than the molar heat capacity of a diatomic ideal gas.
  c. does not depend on which monatomic gas is used.
  d. depends on the molecule's rotation.

Question 2

The Maxwell velocity distribution indicates that
 

 

a.the total translational kinetic energy of all of the molecules in a sample of an ideal gas is (3/2)(kT)(V).
  b.the mean velocity of the molecules in a sample of an ideal gas in any one direction is zero.
  c.molecules of an ideal gas move with the same velocity at a given temperature regardless of molecular mass.
  d.it is impossible to know the mean velocity of the molecules in the sample.


  e. the energy of a molecule of an ideal gas depends more on its position than on its velocity.

Answer to Question 1

c.
This statement is true. The molar heat capacity of a monatomic ideal gas is 3R/2, independent of which molecule is used.

Answer to Question 2

b.
The velocity includes the direction. The average of the velocity, therefore, should be zero since there is no preferred direction for the random assortment of speeds to be traveling
